Answer:
A. 13, 10, 16
Step-by-step explanation:
If three sides of triangle have measures a, b and c, then

Check all options:
A. a=13, b=10, c=16
Thus,

This option is true
B. a=1, b=2, c=3
Then
but
must be greater than c, so
this option is false
C. a=5.2, b=11, c=4.9
Then
but
must be greater than b, so
this option is false
D. a=208, b=9, c=219
Then
but
must be greater than c, so
this option is false

Answer:
=−5x2+18x−13
Step-by-step explanation:
Let's simplify step-by-step.
x2−1−3(2x−2)(x−2)
Distribute:
=x2+−1+−6x2+18x+−12
Combine Like Terms:
=x2+−1+−6x2+18x+−12
=(x2+−6x2)+(18x)+(−1+−12)
=−5x2+18x+−13
Answer:
=−5x2+18x−13
